do you have any idea how much an arduino BT costs? Hint, its $150.

I actually put a serial<->tcp proxy together, back in 2008 (like that post you responded to), also:
Arduino playground - JavaProxy

and used that to communicate with an atmega from python/web pages/whatever. But tcp and bluetooth is all pretty much overkill for a car when you can just read the serial port with a couple feet of wire.

Also, the guino is already transmitting injector/distance data. the obduino may be sending even more data (no lack of data on the actual obd and can busses either).

I think writing a can bus to sort-of-can-like protocol over tcp over bluetooth based "mpg gauge", for $200, is kinda rube goldbergish at best. Keep us posted
